ADJUSTING THE BACKPACK
The backpack has a number of straps that let you adjust your
load for maximum comfort .
Frame
The adjustable frame allows you to position the straps to fit
your body .
1 . Loosen and pull out the Velcro closure .
2 . Put the harness strap into the right position, then lace the
straps through the 4 attachment loops . Tighten the strap
and secure the Velcro closure .
Hip Belt
1 . Loosen all of the straps on the harness system and
position the hip belt so the top of the iliac crest is about
1” down from the top of the hip belt . Correct positioning
will direct the weight onto your hips .
2 . Put the pack on your back so that the hip belt is resting
over your hip bones .
3 . Close the hip belt buckle and tighten it .
4 . Check the padded sections of the hip belt to make sure
they wrap around your hips comfortably . Keep at least 1"
of clearance on either side of the center buckle .
Shoulder Straps
Pull down and back on the ends of the shoulder straps to
tighten them .
Shoulder straps should fit closely to hold the pack body
against your back, keeping the load forward . They should
NOT carry the weight .
Load Lifters
Load-lifter straps are located just below the tops of your
shoulders (near your collarbones) and should angle back
toward the pack body at a 45° angle .
Gently snug the load-lifter straps to pull weight off your
shoulders . (Overtightening the load lifters will cause a gap to
form between your shoulders and the shoulder straps .)
Sternum Strap
Adjust the sternum strap as needed to a comfortable height
across your chest .
Buckle the sternum strap and tighten until the shoulder
straps are pulled inwards comfortably from your shoulders,
allowing your arms to move freely .
Pull the stabilizer straps located on either side of the hip
belt to snug the pack body toward the hip belt and stabilize
the load .
Final Tweaks
Pull the stabilizer straps, located on either side of the hip
belt, to snug the pack body toward the hip belt and stabilize
the load .
Go back to the shoulder straps and carefully take a bit of
tension off of them . This ensures the majority of the weight is
carried by your hips .
